Download
Compiling from source
Download the source code from the files area on Sourceforge.
Ensure that you have the necessary packages to compile programs that use libusb (on Debian or Ubuntu systems, you might need to do apt-get install libusb-dev). After that, unpack and compile the source code with:
tar xvfz mspdebug-version.tar.gz
cd mspdebug-version
make
If you don't want GNU readline support, you can invoke make with:
make WITHOUT_READLINE=1
After compiling, install the binary and manual page by running (as root):
make install
Type mspdebug --help for usage instructions.
RPM packages
RPMs for MSPDebug are available for Fedora (since FC12).
